Thanks for the tips guys!

I think my biggest mistake is I'm trying to focus on making it too detailed at the model level. I keep forgetting that as far as game design goes a lot of what I'm trying to do will be handled with normal/displacement maps and clever texturing so trying to model it like I am is overkill.

I think for the moment I'm going to finish up the other parts then go back through and give the hands an overhaul using the tips and advice you guys gave me. Thanks Bullet, Chirone and Daverave!
